Of course I agree that this is what he should be doing, but I have a
different approach to yours, and I am uncertain why you do it as you
describe...
...
Enter the amount in BOTH amount fields, and THIS IS VERY IMPORTANT,
DO
NOT SKIP THIS STEP, tick the select box, between the "amount due" and
the "amount" fields of the table line items.
I advise you NOT to click "update" at this stage, but instead:
Click post.
Here is where our methods differ: if you only check the box(es),
and then
select "update", the program should fill in the proper amounts.
You may then update further to your heart's content, and finally
select
post.
Only if you are paying fractional invoices, should you need to do
anything
with the amount fields.
